DETA'CHABLE s P'RlN-G-HINGE.

SPECIFICATION forming part of Letters Patent No. 694,670, dated March 41902.

Application filed October 14, 190l- To aZZ whom it nwy concern:

Be it known that I, GEORGE H. SOHIEK, a citizen of the United States,residing at Joliet, in the county of Will and State of Illinois, haveinvented a new and useful Improvement in DetachableSpring-Hinges, ofwhich the following is a specification.

My. invention relates to improvements in spring-hinges for use uponscreen-doors or the like, where it is desired to render the hingedetachable.

My object is to provide a detachable springhinge of a construction whichwill render its leaves readily separable; and it is'further my object toprovide such a hinge of a particularly simple, durable, and inexpensiveconstruction.

In the drawings, Figure l is a plan view of my improved detachablespring-hinge; Figs. 2 and 3, sections on lines 2 and 3 in Fig. l, andFig. 4 a plan view of the hinge members or leaves separated from eachother.

A B are the leaves of the hinge,.each provided with the usualscrew-holes a. On the end of theleaf A are flanged and projecting earsI) b to embrace similar flanged and projecting ears 0 on the leaf B; Theears are provided with perforations to register with each other when theleaves are fitted together. The leaf A isprovided in its edge with arecess d. The leaf B is formed with a projecting arched housing part e.

O is a coiled spring, having bent offsets fg and straight ends 71 h.When passed at its ends through the perforated ears of the leaves, thespring also operates as the pintle to'hold the leaves together inpivotal relation. The olfsets g g bear, respectively, against theopposite leaves and tend to hold them open. The ofisets f presentprojections by means of which the spring may be readily contracted inlength to enable it to be passed into or removed from operativeposition. The part c operates as a housing for the spring and preventsits buckling in use.

Serial No. 78,557. (No model.)

To fasten the leaves together, it is only necessary to grasp the springat theoffsetsf, contract it, and then allow it to expand when the leavesare brought together to pass through the perforated ears. To separatethe leaves, the spring is contracted in the same .way. The spring neednot be removed from the leaf B.

It will be seen that-my improved detachable spring-hinge is formed ofbut three members-the two leaves and the spring-making a constructionthat is particularly simple and inexpensive, as well as durable andedective, for its purpose.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a detachable spring-hinge, the combination of companion leavesformed at their ends with perforated, overlapping ears, and a coiledspring having anoifset toward each end bearing against the respectiveleaves, and

end bearing against the respective leaves, an

ofiset f, and ends passing through the perfo= rated ears, the" springbeing longitudinally contractible whereby it may be readily placed inand removed from its position, and operates as the pintle for securingthe leaves pivotally together.
